Using CreateThread in VC++ Form

1 New Member
Hi,

I am designing a GUI application using a VC++ 2005 Form template. I have created a thread function external to the class containing the form. I can successfully create the thread and run operations in the thread function, but I want to be able to call member functions in the Form from the thread process. In order to do this, I plan on passing a pointer to the object (i.e. the form) as one of the CreateThread parameters. My CreateThread call from within the form is as follows:

networkHandle = CreateThread(NU LL, 0, networkQuery, (LPVOID)this, CREATE_SUSPENDE D, &threadIdent );

However, when I try this, I get an error that reads:

Error 8 error C2440: 'type cast' : cannot convert from 'display_module ::Form1 ^const ' to 'void *'

I imagine this is quite a simple issue (I am, admittedly, very much a newbie) but I haven't been able to find anything online that addresses issues with a CreateThread call from a form. Any help that can be provided would be much appreciated.

Thanks in advance,
Liam

My main app calls LoadLibrary() to load a DLL, which calls CreateThread(). This does NOT return NULL and I get a thread ID. However, ThreadProc never gets executed when this code is in the DLL. It works fine in the standalone EXE source. I put example code below. #define MB(msg) MessageBox(0, msg, "", MB_OK|MB_ICONINFORMATION); DWORD APIENTRY tproc() {

Hi All, I'm new to VC++.net and I searched through the forums and couldn't find anything related to this. I'm trying to send a flat file from a VC++.net program to a PHP file residing on a webserver. I know you can call a website from VC++.net, but I'm not sure how to send a physical file over the internet. I mean is there a way to mimic a normal html form to upload a file, using VC++.net?

Hello, I need to implement a Thread in a Visual C++ 6.0 application. I've never done this, then I've been investigating, but I don't have any properly solution.

Hello all, I am quite new to c++/. Net so please don't shoot me down for being a newbie. Any way I am trying to make a simple multithreading program that is just to learn the ideas behind it (before I incorporate them in another program). I just can’t seem to get a non-static call to work in my thread that has access to the Form1 variables and controls I need. I can call a non-static function using another class but then I can seem to get in...

For most users, this new feature is actually very convenient. If you want to control the update process,...

Let's talk about the concept of autonomous AI software engineers and no-code agents. These AIs are designed to manage the entire lifecycle of a software development project—planning, coding, testing, and deployment—without human intervention. Imagine an AI that can take a project description, break it down, write the code, debug it, and then launch it, all on its own.... Now, this would greatly impact the work of software developers.
